Society as we know it is dead, the world has changed, and everyone has the choice between adapting immediately or disappearing. A few survivors have taken refuge in a shelter away from outside dangers. Their survival is ensured by a machine that produces electricity, an extremely rare resource in these desolate times. One morning, the group discovers with horror that their machine has been destroyed. The hunting party is on: the six companions must venture outside their shelter and immediately find a cable to operate the machine. This expedition, on which their survival depends, will lead them straight to a mysterious group of individuals who intend to prevent them from returning home.
